document.write( "n minus 1 divided by 2 equals 17, how to solve for n? how do u start to solve?\r\n" );
document.write( "\r\n" );
document.write( "Answer:\r\n" );
document.write( "Translate the words, \"n minus 1 divided by 2 equals 17,\" into an equation.\r\n" );
document.write( "\r\n" );
document.write( "We write \"n minus 1\" as \"n-1\".\r\n" );
document.write( "\r\n" );
document.write( "Dividing this by two gives us the expression, \"%28n-1%29%2F2\".\r\n" );
document.write( "\r\n" );
document.write( "Now we set this expression equal to 17. Here's the whole equation:\r\n" );
document.write( "\"%28n-1%29%2F2=17\"\r\n" );
document.write( "\r\n" );
document.write( "Now we'll solve for n. Multiply both sides of the equation by 2.\r\n" );
document.write( "\r\n" );
document.write( "\"2%2A%28%28n-1%29%2F2%29=2%2A17\"\r\n" );
document.write( "\r\n" );
document.write( "One the left side, we divided n-1 by 2, and we multiplied it by 2. These operations undo each \r\n" );
document.write( "other and we have just n-1. On the right side, 2*17 is 34. So,\r\n" );
document.write( "\"n-1=34\"\r\n" );
document.write( "\r\n" );
document.write( "We want n by itself on the left side. We have n minus 1. We undo \"minus 1\" by \"adding 1.\" \r\n" );
document.write( "Remember that we need to add 1 to both sides to get an equivalent equation.\r\n" );
document.write( "\r\n" );
document.write( "\"n-1%2B1=34%2B1\"\r\n" );
document.write( "\r\n" );
document.write( "Simplify; n-1+1 is just n. 34+1 is 35.\r\n" );
document.write( "\"n=35\"\r\n" );
document.write( "\r\n" );
document.write( "Always check your work in word problems. Go back to the original words.Replace n with 35. \r\n" );
document.write( "\"35 minus 1 divided by 2 equals 17.\" Hmmm...35 minus 1 is 34; 34 divided by 2 is 17. Check!\r\n" );
document.write( "\r\n" );
document.write( "That's it!\r\n" );
